I'll be uploading this newest pAVrecord version once testing is complete sometimes tomorrow.

Note: I've included a button to bring up xwininfo with this new version so easy to find window coordinates manually with that. Could also start up say an rxvt window, size that to the precise area you want to capture and then use xwininfo to note the coordinates and offsets of that area prior to closing the rxvt and then capturing that selected screen area. Certainly not an automatic method, since the user still has to manually enter the discovered values, but I find it works okay in practice.

I suggest trying VideoBitrate value 512 kbps, which is the default if the entry box is left blank. That provides fairly good quality for most encoders.
For highest quality screencasts along with small resultant filesize, I suggest selecting x264 encoder. Even VideoBitrates as low as 128 (in kbps), using scast framerate of 10 fps, seemed to give reasonable results and small filesize. Once you have set the screencast parameters you wish to use, I recommend pressing the button that returns to "Small GUI", prior to starting the actual screencast capture.

Note well that for a given video bit rate you will get higher quality encoding if you reduce the frame rate. In other words, for a given video bit rate you can trade frame rate for quality whilst keeping the same recorded video filesize.

If you want variable bit rate video mode instead of the default constant bit rate video mode, enter a value less than 32 into the VariableBitrate box. pAVrecord then automatically uses vbr and the VariableBitrate value is used as the quality setting (using ffmpeg -qscale internally). A medium quality value of 5 works quite well with most codecs. 10 provides highest quality for Theora encoder (different encoders respond differently to qscale values between 1 and 31; with some encoders, quality goes down for larger qscale value, for some it goes up - you need to experiment...).

Come back here, William, Vokoscreen was a dead topic of mine. As Vokoscreen is known better on the web than PAVrecord, it was for pulling future customers to your Puppy special application !
I am still typing in WOLX 2014, a french derivative of Wary. Tests on this distro are ok, consider that p.AVrecord will run on WARY and Racy.

About spanish hand, VLC needs FFMPEG stuff to run pAVrecord, VLC Version ... don't remember right now. It was Puppy es Night LXDE RC3, a very nice spanish distro ... With only VLC as media-player.

Screencasting is my interest, right. later i will certainly use my video camera, but right now, i translate tutorials from english and it's boring. It's much more fun to do it via videos and audio comments
Mais mes leaders du forum francophone ne veulent pas entendre parler de YouTube !

Description

10 fps is the cheaper, and enough. But 30 for video is too low, acceptable however, 120 or 150framerate would be an useful investment, even for a scottish !

I still say that improving screencast capability (e.g. using mouse to specify screencast region of interest) should proceed as an addon module for pavrecord via its 'hijack' facility or as a separate app dedicated to screencast recording since a specialised user interface can more easily be designed for that. pAVrecord can provide the basic functions required for the dedicated app but shouldn't become more bloated itself from its general purpose design (except via these possible addon modules).

About screencasting area, I am thinking about it. Merge Xvidcap for the GUI with pAVrecord, with a little bit of Drec, that would be find.
The big Bug, is the poor pelo is not a Linuxman.... a Lumixman.
Your work is a big step in renewing apps in Puppy. Thanks again, William, we shall see 'la cerise sur le gâteau' (the icing on the cake) later...Rome was not built in a day!_________________Dr Pelo : qui va Puppy va sano. .

But 30 for video is too low, acceptable however, 120 or 150framerate would be an useful investment, even for a scottish !

But I don't think most webcams use a frame rate greater than 30 fps? Or perhaps it is only mine. User can just type '120' in the box if they want that and their video hardware supports it. The reason I hesitate to add mouse defining screencast area is that the user interface is already full and I hesitate to employ extra 'pop up' (or tabbed) config gui's to cater for more functionality - partly because I'm feeling lazy to write so much extra code (and I see a separate cut-down specialised pAVrecord for screencast only, renamed, as a better, more streamlined solution for the specialist such as you, Pelo). Maybe someday... ;-)

The last effort....
30fps for a webcam, i don't know. i was not speaking about webcams, it's an error of me. I study the subject deeper.in fact i should have say variable bit rate.
pAVrecord sets size as 852x480 as i want : it's a big plus, avoiding a later transformation.
I am unable to do it, unless i study Linux jargon...
Say, for next winter in new Zealand, or better next winter in Scotland...
En tout cas, merci de votre convivialité._________________Dr Pelo : qui va Puppy va sano. .Edited_times_total

Okay, it won't be right now, but I'll push that ahead in my coding priorities for later.

I am trying to connect my desktop to a projector which has no physical video input, there is only eshare (dlna) built in. It is an i- codis CB-100 running on android 4.2.2. It is pocket sized yet projects a 60" image on a wall and looks great! Cost me £140. It does have fulll and micro usb sockets and micro-sd card reader built in. The sound is great for such a small device, and comes with a tripod, and is very light and pocketable.

Problem is I want to project my desktop through it primarily for powerpoint presentations. Using chromium browser and vGet Cast dlna, I can play video and music through it.

Theory: Would it be possible to start PAvrecord recording an video file (without sound is ok) and immediately select the file to send over dlna to the projector. The idea is that the format of the file being created and the dlna stream match so that there is as little latency as possible between changing slides etc and viewing that on the projector.
